Y IMPROVEMENT IN HVDRANTS.

Specification forming part of Letters Patent No. 124,777, dated March 19, 1872.

SPECIFICATION. To all whom 'it may concern:

Be it known that I, GEORGE C. BAILEY, of Pittsburg, in the county ofAlleghen y and State of Pennsylvania, have invented a new and usethe cut-oftl and water-escape arrangements of hydrants and stop-cocks.

To enable others skilled in the art to make and. use my improvement, I will describe its construction and operation. v

The outer shell A is of the ordinary construction, and has an opening near the bottom for the admission of the supply-pipe B, which leads up into a valveechamber, C. The upper end of thechamber C opens into a bellmouthed watenway, D, which is secured to the end of the pipe E leading to the discharge-pipe F. In'a groove just inside of the overlapping-lip D' of the bell-mouthed water-way D is washer G, which, when the hydrant is open, rests upon the seat H. At the mouth of the water-way D are a number of openings, I, through which the water passes up to the pipe E. Inthe center of the mouth of the water-way is a threaded aperture, Y, intowhich is screwed a Ythreaded stem, K; made loose so as to work easily. On the lower end of the stein K is a valve, L, having a washer, L', which, when the valve isV closed, rests on the valve-seat M, making a tight joint. Projecting from opposite sides of the valve L are two pins or 1ugs,.

N, which enter and operate in corresponding vertical grooves in the sides of the chamber C, to prevent the valve L from turning therein. Around the upper part of the pipe E is placed a spiral spring, O, which, pressing against the shoulder O', holds .the water-way D down upon the seat H. The same purpose j may be `attained by placing sutticient weight upon the rod, but a spring is preferable. The

top or cap-piece P ofthe hydrant, against which the ripper end of the spring O passes, is secured to the shell A by means of the collar Q in such a Way as to leave the .collar free to turn. The discharge-pipe F projects from the cap P through a proper opening. The collar Q is secured in place by means of the screws Q', which enter the grooves A', and can be adjusted at any desired point. The valve L is opened by rotating the Water-way D, which, turning upon the thread on the stem K, causes the valve to raise oft' the seat M. The waterway D is turned by means of the dischargepipe F, which is used as ahandle, bein g rigidly attached to the pipe E. The cap P is loosely held in place by the collar Q, so as to turn with the pipe F and not interfere with its operation. If the water-way is rotated in the opposite direction, the valve L will be closed and the iiow of water stopped. The further H`rotation of the water-way in the same direction causes it to be raised off of the seat H, and opens a passage between the seat H and washer G for the escape of the water remaining in the pipe E. If so desired, small holes, as at R, can be made through the seat H, to facilitate the escape of the water. l

By this means all the water remaining in the hydrant above the valve-chamber is allowed to escape without the employment of independent devices for that purpose. By the arrangements above described the stream of water from the discharge-pipe F may be directed to any desired point.

Fig.` 4 shows a modification of the same de-A vice as applicable to a stop-cock in that class of faucets or cocks in which itis necessary to make provision to allow the escape of the Waste-water.

' The application ofthe hereinbefore-described device is as follows: The water being stoppedl off by rotating the stem Z, the washer G is closed upon the seat H, shutting the waste-escape. The further' rotation lifts the valve L with its washer L' from oi' the seat M, and allows the passage of the water from the supply B into the dischargepipe F. Reversing the motion of the stem Z brings the different parts into the position shown in the drawin g the supply-pipe closed at M M, and the washer Gr raised from its seat H-allowing the water in the discharge-pipe F to escape, as shown by the small arrow, through the Waste-passage 1t. Instead of closing the Waste by the -Washer G, the same purpose may be attained by having the sea-t H and iiange on the stem Z ground, so that they Will fit against each other and forni a Verfeot joint.

What I o aim as my invention, and desire to secure by Letters Patent, is-

l. A vertically-lift non-rotatin g valve, L, in combination with the valve-seat M and revolving water-Way, substantially as described.

2. In combination with a bell-mouthed Water-Way, ,1), which, in operation, performs the function of a Water-Waste, and the annular seat H, a spring, O, or equivalent device, substantially as described.

3. The combination of the spring O, bell mouth D, and seat H, with the screw K, valve L, valve-chamber C, and seat M, when arranged as shown.

4. A revolving top, swiveled to the hydrantcase and havin g no vertical motion, in combination with a. revolving spout and water-Way and spring O, substantially as'deseribed.

In testimony whereof I, the said GEORGE C. BAILEY, have hereunto set my hand.
